If you are looking for fast, pure pleasure and a kwik build, try the WM T-34, many racing those. If you are looking for a little more scale, you can try the WM P-51. If you are looking for pure speed, you can try the WM Dago Red.

As you can see, I am sold on WM. I have had many of their ARFs and nothing matches the ease of assembly of these plane. You can easily put a SS40S together in an afternoon.

My 2 cents
